| phylum | Chordata | Monoclonius is a dubious genus of herbivorous ceratopsian dinosaurs found in the Late Cretaceous layers of the Judith River Formation in Montana. Monoclonius was named by Edward Drinker Cope in 1876. Later, much taxonomic confusion was caused by the discovery of Centrosaurus, a very similar genus of ceratopsian, that is known from much better remains. Today, most Monoclonius specimens are usually believed to be juvenile or subadult Centrosaurus. Monoclonius proper is now usually considered a nomen dubium, pending further study.
